MITAB 1.6.1 has just been released and posted to the website at http://mitab.maptools.org/
The main change in this release is the addition of a "Quick Spatial Index Mode" which addresses the slow write performance introduced by the optimized spatial index generation code in version 1.6.0. The new "quick" mode (not enabled by default) generates a non-optimal spatial index (similar to MITAB 1.5 and older) but results in faster write time than the optimized index generated by v1.6.0+. For the full details, see bug 1669: http://bugzilla.maptools.org/show_bug.cgi?id=1669#c1 This new release also contains a few important fixes to the support for collection features that was introduced in MITAB 1.5. MITAB 1.5 to 1.6.0 may produce corrupt files when writing collections, so users of those versions are strongly advised to upgrade to 1.6.1. Thanks to Safe Software for funding the work on the "quick spatial index mode" and the bug fixes above. The complete list of fixes/changes since 1.6.0 is included below. Daniel Version 1.6.1 (2007-03-30) -------------------------- - Added "Quick Spatial Index Mode" which generates a non-optimal spatial index (similar to MITAB 1.5 and older) but results in faster write time than the optimized index generated by v1.6.0+ (bug 1669) (Thanks to Safe Software for funding this.) - Added mitab_c_set_quick_spatial_index_mode() to C API (bug 1669) - Fixed problem writing collections where MITAB was sometimes trying to read past EOF in write mode (bug 1657). - Fixed another problem writing collections when the header of objects part of a collection were split on multiple blocks (bug 1663) - Added missing NULL pointer checks in SetPenFromStyleString(), SetBrushFromStyleString() and SetSymbolFromStyleString() (bug 1670) Yahoo!
